Felix the Cat converts himself info pure energy to travel through the Trans-Atlantic Cable as a Morse Code blip, nearly gets eaten, clobbered, (and enmeshed in some mild blackface humor) along the way, all to find out whether "Man Came from Monkeys." Pretty cool.

This one has a plot that’s farfetched even for a Felix cartoon. Felix agrees to go to Africa to find out if man evolved from monkeys, so he can split the reward money with a guy who tells him about a contest that pays money to whoever can find proof of evolution. So Felix sends himself by transatlantic cable to Africa (in a very clever sequence), where he discovers a “family tree” full of monkeys. The monkeys are offended by the idea that humans are their relatives and so they chase Felix back across the cable. This is an incredibly silly Felix, as you may deduce from this plot description, and that makes it fun, of course.
